Question

An electric heater takes 6 A current from 220 V supply line. Calculate the power of heater and electric energy consumed by it in 2 hour.

Answer 1

May this answer will help you.

Answer 2

GIVEN

• Voltage (V) = 220 V
• Current (I) = 6 A
• Time (t) = 2 h = 2 x 60 x 60 = 7200 s

FORMULA TO BE USED

• P = V × I
• Energy consumed by the motor = P x t

POWER CALCULATION

• P = 220 x 6
• P = 1320 W

ENERGY CALCULATION

• E = 1320 x 7200
• E = 9.504 x 10⁶ J

RESULTS

• Power of the motor = 1320 W
• Energy consumed by the motor = 9.504 x 10⁶ J
